I wrote a single python script for transferring data. import serial import os ## python -m serial.tools.list_ports -- listing ports ser = serial.Serial('COM11',115200) print(ser.is_open) file_size = os.path.getsize("<file_path>") print(file_size) with open('<file_path>', 'rb') as file: while True: data = file.read(128) # Read 128 bytes at a time #print(data) if not data: break ser.write(data) print("Broke from the loop") print("finished transferring") print(ser.read()) response = ser.read(file_size) print(response) ser.close() The files are transferring to the zedboard but not the other way around. What is my mistake here? Earlier working code was a simple file check #include <stdio.h> #include "platform.h" #include "xil_printf.h" #include "xuartps.h" #define NUM_OF_BYTE 5 XUartPs_Config *Config_0; XUartPs Uart_PS_0; XUartPs_Config *Config_1; XUartPs Uart_PS_1; char test[] = "Hello"; char hacked_string[] = "Hacked"; int main() { init_platform(); int Status; //u8 BufferPtr_tx[10]={'1','2','3','4',5,6,7,8,9,10}; u8 BufferPtr_rx[]={0}; u8 check[NUM_OF_BYTE] = {0,0,0,0,0}; /************************* * UART 1 initialization * *************************/ Config_1 = XUartPs_LookupConfig(XPAR_PS7_UART_1_DEVICE_ID); if (NULL == Config_1) { return XST_FAILURE; } Status = XUartPs_CfgInitialize(&Uart_PS_1, Config_1, Config_1->BaseAddress); if (Status != XST_SUCCESS) { return XST_FAILURE; } while(1){ // // for(int i =0;i<NUM_OF_BYTE;i++) // { // XUartPs_Recv(&Uart_PS_1, *check[i], 1); // } XUartPs_Send(&Uart_PS_1, check, (NUM_OF_BYTE)); Status = -1; while (Status < NUM_OF_BYTE) { Status += XUartPs_Recv(&Uart_PS_1, BufferPtr_rx, 1); if(BufferPtr_rx[0] != '\n'){ check[Status] = BufferPtr_rx[0]; } //Status++;//Status += XUartPs_Recv(&Uart_PS_1, BufferPtr_rx, (NUM_OF_BYTE - Status)); } //XUartPs_Send(&Uart_PS_1, check, (NUM_OF_BYTE)); for(int i =0;i<NUM_OF_BYTE;i++) { xil_printf("check : %c",check[i]); } if(memcmp(check,test,NUM_OF_BYTE) == 0 ){ xil_printf("Success!!"); XUartPs_Send(&Uart_PS_1, hacked_string, 7); } else { printf("What?!"); } } cleanup_platform(); return 0; } This code was working with the exact output but not the previous code. I am sry if this too lengthy
